I have several bows that wouldn't permit the normal mounting of a Kwik-Loc, so I reverse mounted them to hold the arrow at the front of the riser.
To release it and shoot, I grasp the nock of the arrow and push the string forward about one inch before drawing.
I think of it as if it were my "safety," and the first thing I do when an animal comes into site I may decide to shoot is "take the safety off."
I have been doing this for years and it has worked very well for me. In fact, I have set all my bows up this way so everything is consistent and I never have to think about it. YMMV, but it's been a winning method for me...
